This paper, drawing on original sources, provides an overview of and a discussion on those writings and ideas, in Antonio Gramsci's huge corpus of work, that are relevant to the education of adults. This should provide a fitting tribute to this major social theorist of the 20th century on the 70th anniversary of his death. Among the topics discussed are those of adult education for industrial democracy, adult education and cultural preparation, adult literacy, prison education, adult education and the Southern Question with specific reference to immigration, and, most important of all, adult education in the context of an intellectual and moral reform.
